-RIVETING DEV ICE.

SPECIFIGATIQN forming part of Letters Patent No. 786,778, dated. April 4, 1905. I I Application filed July 5, 1904. Serial No. 215,393.

To all whom, it may concern."

Be it known that I, FRANK SHEPPARD, a citizen of the United States, residing at Edwards.

ville, Madisoncounty, State of Illinois, have invented certain new and useful Improvements in Riveting Devices, of which the followingis aspecification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. My invention relates to improvements in riveting devices; and it consists of the novel features herein shown. described, and claimed. In the drawings, Figure 1 is a perspective of my riveting device, parts being shown in section to illustrate the construction. Fig. 2 is a top plan view of the device shown in Fig. 1. Fig. 3 is a bottom plan view of the device shown in Fig. 1. on the line 4 4 of Fig. 1 and looking in the direction indicated by the arrow.

Referring to the drawings in detail, the main frame of my improved'riveting device is cast in a single piece and comprises means of forming the rivet-chamber 5, the punch-chamber 6, and the rivet-set chamber 7 said chambers being arranged side by side in vertical positions and normally open at both ends. A cover 8 is hinged to the frame and in position to cover the chambers and '6, and a springcatch 9 is secured to the side of the frame in position to hold the cover closed. The stopslot 10 extends through the front wall of the frame from the rivet-set chamber 7 at its lower end. The washer-holding plate 11 is secured to the bottom of the frame in position to close the lower ends of the chambers 5, 6, and 7,

there being a rivet-slot 12 in said plate at the lower end of the chamber 7 and said plate forming the rivet-set stop 13 across the lower end of the slot 10. The rivet-set 14 is slidingly mounted in the rivet-setphamber 7, and the rivet-set stop-pin 15 extends from the rivet-set through the slot 10, said stop-pin engaging the rivet-set stop 13 to limit the down Ward motionof the rivet-set and said pin engaging the upper end of the slot 10 to limit the upward motion of the rivet-set, thereby allowing the 'r-ivet-set to slide up, and down in Fig. 4 is a sectional detail.

rivet-set stop 13 is not required as a set-stop; I

but I prefer to form the plate 11 with the portion 13 extending across the end of the slot 12, as shown in Fig. 1.

In the operating'of my improved riveting device rivets and washers may. be placed in the chamber 5, the punch for making holes for the rivets may be placed in the chamber 6, the cover closed and held closed by the catch 9. I

When it is desired to splice a harness-strap or the like, the cover 8 is opened, the punch is removed, the holes are formed in the straps, a rivet and washer is removed from the chamber 5 and placed in the holes in the straps. Then the riveting device is placed in position With the point of the rivet extending through the slot 12 and the edges of the plate around and the head of the rivet-set is struck with a hammer to form a head upon the rivet above the washer. Then the device is removed,- the punch returned to its chamber,-and the cover 8 closed.

I claim 1. In a riveting device: a suitable frame forming a rivet-chamber, a punch-chamber, and a rivet-set chamber; there being an opening at the bottom of the rivet-set chamber to receive the point of the rivet; and a rivet-set slidingly mounted in said rivet-set chamber above said opening; substantially as specified.

2. In a riveting device: a casting forming a rivet-chamber, a punch-chamber, and a rivetset chamber; a cover hinged in position to close the rivet-chamber and the punch-chamaround the rivet and a rivet-set mounted. in the rivet-set chamber above the slot in said washer-holding plate.

In testimony whereof I have signed m y name I 5 to this specification in presence of two subscribing witnesses.

FRANK SHEPPARD.
